DESCRIPTION OF THE SENSOR

LOOPS  INSTALLATION TIPS

A. CABLE SPECIFICATIONS FOR LOOP AND FEEDER

• 1 .5 mm 2 cross section area

• Multi-strand cable

• Insulation material : PVC or Silicone
  Product compliance

• For the feeder cable, the wire must be twisted at least 15 times by meter
  R& TTE 1999/5/EC
  EMC 2004/108/EC
  UL listed equipment for UL 508

• Feeder for long runs used for foil screened cable is recommended (earth at equipment end only)

• The feeder cable must be firmly fixed to avoid any false detection (max length : 100 m)

• Waterproof cable junction box is required

B. LOOP GEOMETRY

• With two adjacent loops connected to a dual channel sensor, it is possible for these loops to share a common slot, if so required.
  As the channels are multiplexed, no interference will occur.

• Avoid large loops or long feeder (max 100 m), the sensitivity will be affected.

C. DETERMINATION OF THE NUMBER OF LOOP TU

WARNING:

For conformity reasons, in any situation, the antenna factor defined as the loop surface multiplied by the number of turns should not exceed NA= 20

For example, if L=2m, Ea= 1 m and the number of turns=4, then the NA= 2×1 x4 = 8 < 20.
Find hereafter the recommended values for the turns :

ADJUSTMENTS

A. THE 3 CONFIGURATIONS

• Configuration # 1 : single loop detector (MATRIX-3-S)
• Configuration # 2 : dual loop detector in independent mode (MATRIX-3-D with dip switch #10 OFF)
• Configuration # 3 : dual loop detector in combined mode (MATRIX-3-D with dip switch #10 ON)

B. POTENTIOMETERS

PRESENCE TIME

SENSITIVITY

• A potentiometer for adjustment of the maximum duration of a presence detection :
  from 1 min to infinity

• A potentiometer for adjustment of the linear sensitivity (Δf) for the loop A :
  from 0.005% to 0.5 %

• A potentiometer for adjustment of the linear sensitivity (Δf) for the loop B :
  from 0.005% to 0.5 %

C. RELAY CONFIGURATIONS (Dip Switch #3)

The loop A activates the relay A and the loop B activates the relay B. With the dual loops in combined mode the relay A provides the presence detection and the relay B provides the movement direction

| ACTIVE MODE (dip switch #3 OFF)| PASSIVE MODE (dip switch #3 ON)
---|---|---
Detection| |
No Detection| |

D. DIP SWITCHES

After each dip switch change the sensor launches a learning process

(with dual loops)
Dip Switch #3| Relay con­figuration : active or passive
Dip Switch #4| Automatic Sensitivity Boost (ASB option) [recommended for better trucks detection] : During a detection the sensitivity increases automatically to 8 times the preset sensitivity given by the sensitivity potentiometer adjustment. It is limited to the maximum sensitivity (Δf = 0.005%). It goes back to the preset value after detection stops.
Dip Switch #5| Relay A function : presence or pulse (not used with dual loop in combined mode)
Dip Switch #6| Relay A Pulse type : entry or exit (used only at pulse function) or Relay B mode (with dual loop in combined mode) (see next drawing) • non-directional : The relay B provides a pulse according to the dip switches

7 and #8 setting. • directional A— B :

The relay B provides a pulse only if the loop A is detecting before the Loop B. The detection takes place according to dip switches #7 and #8 logic

| Warning: During the detection, the 2 loops have to detect simultaneously for a short period to be
able to determine the movement direction. During loop installation make sure the 2 loops are close enough to each other to ensure a common detection (typical 1m).

Dip Switch #7

| Relay B function : presence or pulse or loop selection for relay B pulse : pulse on Loop B or pulse on Loop A (used with dual loop in combined mode)
Dip Switch #8

Dip Switch #9| Pulse duration for both relays (used only at pulse function): 100 ms or 500 ms

LED SIGNAL

• 1 Green LED shows when the module is powered
• 2 Red LEDs give
• the corresponding loop detection state in normal situation
• the value of the oscillation frequency measurement or an error message on power ON

In normal situation the red LED stays ON as long as the loop detects any metallic object

On power ON the sensor measures the oscillation frequency of each loop. The result of this measurement is displayed using the corresponding red LED. The amount of blinking indicates the tens value of the frequency. For example 4 short flashes correspond to a frequency between 40 kHz and 49 kHz. After this message the LED goes back to normal display.
If the loop oscillation frequency falls outside the limits set between 20 kHz and 130 kHz the red LED displays an error message and the sensor activates the corresponding relay. The blinking frequency shows the type of error according to the next table. The sensor will stay in this state until the problem is cleared and the frequency goes to the right range.

Remark: The sensor launches automatically a learning process if the oscillation frequency changes more than 10% in comparison with the measurement value.

TROUBLE-SHOOTING

with dip switches or change loop turns
The loop LED is detecting properly but the contact is not made| Bad connection of the relay contacts| Check relay connections
Dip switches 5 to 8 are not responding properly| Their function varies according to dip switch #10 setting| Check the appropriate loop mode required and adjust dip switch #10
